ProxySQL 排错 Max connect timeout reached while reaching hostgroup 10 after 10000ms
ProxySQL 排错
- 问题分析:
在ProxySQL在集群下,因未知原因导致误测到所有节点OFFLINE_HARD,并runtime_mysql_servers表清空,从而导致前端查询无法传递到后端对应的servers上,重新load mysql servers to runtime可以暂时解决,但没有找到长期解决办法,只好退回单节点模式。如有解决的兄弟希望你分享给我(k2865#qq.com,或讨论区留言 ) - 版本和环境
ProxySQL:

- 故障现像:
ProxySQL 开始最先是正常的.可以读写,通过sysbench 也能正常压测,但随后报以下错误:
FATAL: MySQL error: 9001 "Max connect timeout reached while reaching hostgroup 10 after 10000ms"
(last message repeated 1 times)
FATAL: `thread_init' function failed: /usr/share/sysbench/oltp_common.lua:273: SQL API error
(last message repeated 1 times)
FATAL: mysql_stmt_prepare() failed
FATAL: MySQL error: 9001 "Max connect timeout reached while reaching hostgroup 10 after 10000ms"
FATAL: mysql_stmt_prepare() failed
FATAL: MySQL error: 9001 "Max connect timeout reached while reaching hostgroup 10 after 10000ms"
FATAL: mysql_stmt_prepare() failed
FATAL: MySQL error: 9001 "Max connect timeout reached while reaching hostgroup 10 after 10001ms"
FATAL: mysql_stmt_prepare() failed
- 手工连接,发现直接连接MGR节点是可以正常连接并查询的,连接proxysql,可以登录但无法查询:
wyz@db210 [(none)]>select * from wenyz.t2;
ERROR 9001 (HY000): Max connect timeout reached while reaching hostgroup 11 after 10000ms
wyz@db210 [(none)]>select * from wenyz.t2;
ERROR 9001 (HY000): Max connect timeout reached while reaching hostgroup 11 after 10000ms
查看官方问题库,得以下解释:
11. No Hostgroup 0 has been configured , then why we get "Max connect timeout reached while reaching hostgroup 0 after 10000ms" ?
This is how MySQL Query Rules work while selecting hostgroups.
When you set any query rules inside table mysql_query_rules , Then your query get analyzed by the Query Processor to decide which destination hostgroup it should forward. (according to mysql_query_rules.destination_hostgroup)
When your Query Processor doesn't find any query matching to query rule then the default hostgroup for the specific user is applied (according to mysql_users.default_hostgroup)
Example : Default Hostgroup for User
根据这一信息,查看ProxySQL状态,发现runtime_mysql_servers没有记录.
